Figure 11

Neighbor-Net splits graph based on PBC-inferred distances: Zelkova. A strong (palaeo-) biogeographic pattern is visible, which was established in the course of the evolutionary unfolding of this genus [22]. The placement of each species and individual correlates perfectly with its genetic (considering the potential hybrid individual Zse 2) and evolutionary background, as sketched in [22], and highlighted by coloured edge bundles. Further colours used are: • blue, edge bundle distinguishing between the Chinese Z. schneideriana (and Zse 2 exhibiting Z. schneideriana-type ITS homoeologues) and the closely related other species; • reddish, edge bundles reflecting the evolutionary pathway from Z. carpinifolia (primitive, shares edges with the sister taxon Z. schneideriana) through Z. serrata (more derived, secondary reticulation with Z. schneideriana) towards Z. abelicae and Z. sicula (most derived); • green, edge bundle that correlates with differential relationships between and among Eastern Asian and Western Eurasian extant species, addressed in detail in [22].
